Looking over the plans in the timeline section of that page, it looks like there isn't a general community input section, where people unaffiliated with the bidding or judging process can say things as basic as "I would attend the proposed London Wikimania but would not attend the proposed Arusha one". In fact, there doesn't even appear to be a section in the criteria that accounts for whether the community at large is interested in or opposed to specific bids or bid locations. I realize that the bidding process is not a democracy, and that such a selection criteria would convey significant advantages to cities/countries that have a large number of users or are especially effective at mobilizing users to comment, but if many more users want to go to one location over another, shouldn't that be taken into account?
